I've only been riding for about 12 months, and until the CBT had never sat on a bike. I bought a 125, and shortly afterwards did the theory test and then rode all winds & weathers (apart from the snow & ice!)
With all the scare stories read in MCN I had been putting off doing the test, but then had a chat with a local instructor and we discussed the type of riding I'd been doing etc and we decided that I'd be OK to sign up for their training & test. I decided to do the DAS test.
I was still dreading the Mod 1 test, but as mentioned, the area is huge and well laid out. OK, whether it's entirely representative of real life situations is debatable, but I could debate it all I want - if I want a licence I have to do it.
The hazard avoidance/swerve test went well and was far easier than I'd imagined - I really didn't need to worry. It really isn't difficult & if you can't do this type of manoeuvre you probably shouldn't be on the roads
I presume Dave b had failed to reach the speed twice, or there was some other fault, as if you don't make the speed the first time, you're given a second go at it.
If you're ready for the test, and have put in some work beforehand, it really isn't a problem. I suspect many prospective candidates have been put off applying for their Module 1 as a result of these unfounded (in my opinion) scare stories.
